As described above, according to the descending ridge cap according to the present invention, the descending ridge cap can be attached after the roofing material is finished, so that the workability is good. When nailing the protruding piece for fixing the downhill cap, the concave groove of the floor plate serves as a guide, which prevents the nail from swinging (swimming). Since the down ridge cap is almost the same as the decorative surface of the roofing material, the joint of the down ridge is not divided and the aesthetics are improved. Since the down ridge cap is in surface contact with the roofing material, distortion and pecking do not appear on the decorative surface, and it has good waterproofness. The mounting is performed by inserting the horizontal joint locking portion into the goby portion and the male connecting portion of the roofing material, and further, nailing the fixing projection, so that there is no fear of detachment. Because the roof plate and the down ridge cap face each other appropriately,
The roof plate shape can be arbitrarily formed, and even if water leaks from between the roofing material and the descending ridge cap, rainwater does not diffuse to the base of the roof and can be reliably discharged to the outside. By the side joint locking part of the down ridge cap,
No flapping. There are features and effects such as.
